I think that aqua ven refers to the BHC, because the short knight I think is Xehanort, which is why the E.S. is saying Xehanort alot because he and Sora look alike.
I actually think the RK is Xehanort. 3 reasons. 1, The E.S, is fought by Sora, 2, BHC' armor is in that room with Xemnas, and 3, Xehanort was appartantly young when Ansem found (from the secret Ansem reports and Xigbar).
I think the guy whose eyes change colors is related to Saix. Because in the PV the Org. member in the end has the same build as Saix, and calls the person in armor friend. That person resembles BHC from what I could see, so that's why he's calling her friend.

I think the Keybade the Spider-man look alike is wielding the short AU's Keyblade. At about 55 seconds into the secret ending, you can just barely see his Keyblade, but they look similair. So I think the AU being held up by the Xehanort is the short one and he took the short one's Keyblade and gave it to the Spider-man look alike.
